DIRECTION-SIGNAL FOR MOTOR-VEHICLES.

Specification of Letters Patent.

Patented Nov. 16, 1920.

Application'flled January 16, 1918. Serial No. 212,014.

T 0 all whom it may concern: v

Be it known that I, KING E. S'roKER, a citizen of the United States of America, residing at Stockton, in the county of San Joaquin, State of California, have invented certain new and useful Improvements in Direction-Signals for Motor-Vehicles; and I do declare the following to be a clear, full, and exact description of the same, reference being had to the accom anying drawings, and to the characters 0 reference, marked thereon, which form a part of this application.

This invention relates to improvements in signals for use on motor vehicles designed to indicate when the driver of a vehicle is about to stop or turn in either direction.

The invention particularly relates to improvements upon the structure shown 1n my atent No. 1,226,826.

The object of the invention is to produce a lamp connection for the signal which will light the instant the signal starts toward its extended position. In .the structure of the patent above named, when the signal is drawn up, the lamp lights but, with the vibration of the vehicle if the signal shakes downwardly even to a small degree the lamp will go out. By my improved connection, the lamp remains lighted at all times.

Also, I aim to provide the signal arm so that when it is in itslower position, it will rest immediately adjacent the windshield and hencebe out of the way and not liable to be engaged or broken off by any person or object coming in contact therewith.

Furthermore, the construction by which I attain this object makes a better and more practical signal when extended.

A still further object of the invention is to (produce a simple and inexpensive device an yet one which will be exceedingly effective for the purposes for which it is desi ned. Q

These objects, I accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusal-f of the following specification an m. J On the drawings, similar char'actersi'of reference indicate corresponding parts in the several views.

Figure 1 is a front elevation of a motor vehicle showing my improved signal in 'position thereon. Fig. 2 is a' front elevation of the signal in extended position partly broken out andin section.

F1g. 3 is a diagrammatic view of the techmcal wiring of the signal.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 designates the clamp by means of which the signal is fastened to the edge of the windshield 2. The clamp supports the signal casing 3 which is preferably circular in shape and provided with a slot 4 in its periphery through which projects the signal arm y The slot 4 is of the length of a quarter circle so as to limit the movement of the signal arm in either direction.

The casing 3, of course, projects a considerable distance from the edge of the windshield 2 and it is desirable not to have the signal arm project any farther than is abs0 lutely necessary to its successful operation. To that end when in normal unextended po sition, the signal arm 5 is connected to a central pin 6 within the casing 3 and extends directly downwardly therefrom to its engagement with the lower terminus of'the slot 4. Just outside the casing3 it makes a right an 1e turn, as at 5, which turn extends norma ly to a point closely adjacent the windshield 2 where it makes another right angle turn, as at 5", and extends arallel to the said windshield 2. Within t e casing, the arm 5 is provided with an actuating lever 7 extending at right angles thereto which is provided with acurved core 8 adapted to be drawn into the curved electro-magnet 9 when the signal is to be raised, this latter construction beit g shown in the above named patent. The electrical circuit for exciting the electro-magnet 9 and lighting the lamp 10 within the outer end of the signal arm 5 consists of a wire 11 leading from any source of electrical energy 12 through a switch 13. By means of thls switch, a circuit may be made through a Si al on either side of the car, as shown in ig. 1.

Describing now. the connection of the wiring with one signal, the wire 11 projects into the casing 3 where it branches. One branch 11 leads through the electro magnet 9 and is grounded on the casing 3, as at 14. The other branch 11" extends to the lamp 10 and is grounded through the base of the lamp to.

10 have common ground, the instant the switch 13 is connected to cause the electrical circuit to influence the electro-magnet 9, it will also light the lamp 10 before the signal arm is extended. This will maintain the lamp in lighted condition as long as the signal is extended, which is a great advantage over having it light merely at the time the signal reaches extended position, since, as noted before, the vibration of the car might break the contact points under the latter condition and cause the lamp to become dark, which would render the signal inefi'ective.

From the foregoing description it will readily be seen that 1 have produced such a device as substantially fulfils the objects of the invention as set forth herein.

lVhile this specification sets forth in de tail the present and preferred construction of the device, still in practice, such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claim.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is:

A direction signal comprising a casing adapted to be mounted to the windshield of a vehicle to one side thereof, an arm pivotally mounted in the casing and arranged to be electrically rotated through a quarter revolution, one end of the arm projecting beyond the outer periphery of the casing and in horizontal alinement opposite to the windshield when the arm is rotated, a right angled member fixed to the ends of said arm and projecting substantially to the vertical edge of the windshield when the arm is in a vertical position, and an extension fixed to the outer end of said right angled member at right angles thereto and parallel to the arm, the latter member serving as a signal arm and lying in a horizontal plane when the arm in the casing is rotated.

In testimony whereof I afiix my signature in presence of two witnesses.

KING E. STOKER.
